Study: Methane From Fracking Sites Can Flow to Abandoned Wells

By -
From Phys.org:
As debate roils over EPA regulations proposed this month limiting the release of the potent greenhouse gas methane during fracking operations, a new University of Vermont study funded by the National Science Foundation shows that abandoned oil and gas wells near fracking sites can be conduits for methane escape not currently being measured. 
The study, to be published in Water Resources Research on October 20, demonstrates that fractures in surrounding rock produced by the hydraulic fracturing process are able to connect to preexisting, abandoned oil and gas wells, common in fracking areas, which can provide a pathway to the surface for methane. 
A recent paper published in the Proceedings of the National Academy of Science showed that methane release measured at abandoned wells near fracking sites can be significant but did not investigate how the process occurs. 
"The debate over the new EPA rules needs to take into account the system that fracking operations are frequently part of, which includes a network of abandoned wells that can effectively pipeline methane to the surface," said the new paper's lead author, James Montague, an environmental engineering doctoral student at the University of Vermont, who co-wrote the paper with George Pinder, professor of environmental engineering at the university. 
The study focused on an area in New York State underlain by the Marcellus Shale formation, which had been fracked until a ban went into effect in the state in the summer of 2015.

Fracktivist in Dimock Releases Carefully Edited Video, Refuses to Release the Rest

From Energy in Depth: There is something very strange going on along Carter Road, in Dimock, Pennsylvania, and I’m not speaking of natural gas, methane migration, contamination, litigation or even the extensive water testing there by the EPA and others.  No, I’m talking about a new “Watergate” conspiracy, complete with 18 minutes of missing tape (well, video, actually). It seems the ever-present Green Party member and  naturist   Vera Scroggins  (a/k/a  Vera Duerga ) has posted a video of Craig Sautner meeting with the EPA.  Mysteriously, the video is but 14 seconds in length, cutting off conversation in what is obviously mid-stream.  It raises a question Craig Sautner, like  Ronald Reagan in Kings Row , might have asked, “Where’s the rest of me?’  Carter Road, isn’t Kings Row, of course, (at least not until you arrive at  the mansion Scott Ely, one of the Dimock litigants, is building with his royalty money ), but there appears to be a whole lot of film editing going on there to fi

The Second Largest Oil and Gas Merger - Cabot and Cimarex

       Due to investor pressure, the U.S shale drillers are being pushed to improve financial and operational performance after a few years of poor returns. Even though the industry has improved its numbers, when compared to last year, investors still want more to be done for them to earn more money.      That's why two mid-tier shale drillers, Cabot and Climarex, have decided to merge in order to eliminate $100 million in annual costs, which means more money for the investors. This all-stock transaction is valued at about $7.4 billion, which is relatively high for the oil and gas sector.      The new entity will be renamed and the headquarters located in Houston, Texas. Cabot shareholders will own 49.5 percent of the new entity, and Climarex the rest.       The Cimarex-Cabot merger will address the investor's demand for a higher amount of returning cash. The initial plan is to pay a 50-cent-per-share special dividend on closing the deal while offering a quarterly variable div

Do You Know The History of Fracking?

  In 2018, 59% of total oil production in the U.S came from hydraulic fracking, which means it accounted for more than two-thirds of domestically manufactured gas. By 2024, fracking will reach an astounding $68 billion market value! Of course, fracking is not a new drilling method as you can trace it back hundreds of years. That's why we want to consider the history of hydraulic fracturing (fracking). We will be stating historical facts about it and focusing on the major historical occurrences that have influenced modern-day fracking. Pre-Fracking Days The idea of fracking started back in 1862 when Edward A.L. Roberts (Civil War veteran) witnessed Confederate soldiers exploding artillery rounds into a canal that obstructed a battlefield. At the time, Edward A.L. Roberts called it superincumbent fluid tamping. On April 26th, 1865, Edward A.L. Roberts began experimenting with exploding torpedoes, which consisted of lowering a torpedo containing an amount of powder from fifteen to tw
